Water, Collagen, and Lipid Content in the Human Skin and Muscles Assessed with Near‐Infrared Diffuse Reflectance Spectroscopy and Multi‐Spectral Optoacoustic Tomography [PDF]

open access: yesAdvanced Science
Infrared spectroscopy can quantify individual body components such as lipids, water, and proteins, but extending it to a comprehensive assessment of overall body composition is hampered by high variability and optical heterogeneity of biological tissues.

Optoacoustic imaging of the brain in a cachexia-inducing pancreatic cancer xenograft [PDF]

open access: yesFrontiers in Oncology
Pancreatic cancer-induced cachexia drives co-morbidities that result in a poor quality of life. To expand understanding of the effects of cachexia on the brain here, for the first time, we used noninvasive oxygen enhanced (OE) multispectral optoacoustic ...

Multispectral Opto-acoustic Tomography (MSOT) of the Brain and Glioblastoma Characterization

open access: yesNeuroImage, 2013
Brain research depends strongly on imaging for assessing function and disease in vivo. We examine herein multispectral opto-acoustic tomography (MSOT), a novel technology for high-resolution molecular imaging deep inside tissues. MSOT illuminates tissue with light pulses at multiple wavelengths and detects the acoustic waves generated by the ...

Derivation and validation of a non-invasive optoacoustic imaging biomarker for detection of patients with intermittent claudication [PDF]

open access: yesCommunications Medicine
Background Peripheral arterial disease (PAD) affects more than 200 million people worldwide, with symptoms ranging from none to severe. Despite these different diagnostic options, patients with unclear leg pain remain challenging to diagnose. The primary

Multispectral optoacoustic tomography of benign parotid tumors in vivo: a prospective observational pilot study [PDF]

open access: yesScientific Reports
Parotid lumps are a heterogeneous group of mainly benign but also malignant tumors. Preoperative imaging does not allow a differentiation between tumor types. Multispectral optoacoustic tomography (MSOT) may improve the preoperative diagnostics.

Semi-quantitative Multispectral Optoacoustic Tomography (MSOT) for volumetric PK imaging of gastric emptying

open access: yesPhotoacoustics, 2014
A common side effect of medication is gastrointestinal intolerance. Symptoms can include reduced appetite, diarrhea, constipation, GI inflammation, nausea and vomiting. Such effects often have a dramatic impact on compliance with a treatment regimen. Therefore, characterization of GI tolerance is an important step when establishing a novel therapeutic ...

Application of multispectral optoacoustic tomography for lower limb musculoskeletal sports injuries in adults [PDF]

open access: yesPhotoacoustics
Compositional changes in relation to musculoskeletal injuries are difficult to measure non-invasively. This study aims to use non-invasive label-free imaging with Multispectral Optoacoustic Tomography (MSOT) to evaluate compositional changes with injury.

WST11 Vascular Targeted Photodynamic Therapy Effect Monitoring by Multispectral Optoacoustic Tomography (MSOT) in Mice

open access: yesTheranostics, 2018
Objective: Monitoring emerging vascular-targeted photodynamic therapy (VTP) and understanding the time-dynamics of treatment effects remains challenging. We interrogated whether handheld multispectral optoacoustic tomography (MSOT) could noninvasively monitor the effect of VTP using WST11, a vascular-acting photosensitizer, on tumor tissues over time ...
